CPF_CURRENTPITCH starts swerving towards PTRX_PITCHTARGET as soon as that is set. In practice this means that CPF_FRACADDRESS may acquire a non-zero value before we manage to force CPF_CURRENTPITCH to the final value, which would prevent bit-for-bit reproduction. To avoid that this state persists, we now reset CPF_FRACADDRESS when setting CPF_CURRENTPITCH, and to (mostly) avoid that it progresses too far in the first place (possibly even reaching CCCA_CURRADDR), we write PTRX and CPF in one critical section (though NMIs, etc. still make this unreliable).
